One of the critical factors to consider when purchasing an induction furnace is the types of metals that the furnace can effectively smelt. The overall cost budget also plays a part, especially when investing in selecting a silver melting furnace. However, to run a profitable business, certain elements are overlooked in the choosing of an Induction furnace.  As they are just as important, below are some of the critical factors to keep in mind.

• Efficiency Of The Induction Furnace

When considering which kind of furnace to invest in, focus on the efficiency of the furnace. As the differentiating factor of two furnaces, you should aim to choose one that works better even if both seem to have the same price tag. Ideally, to get an overview of the efficiency, you should consider the kind of special features it has and how it enhances its smelting capabilities. This includes noting down such elements like heat exchange, pressure switches and durability of the crucible with various metals and how it varies from a DIY furnace.

• Induction Furnace Warranty

As with any other product in the world, the kind of warranty a manufacturer offers tells you a lot about the product quality. When investing in the best melting furnace, look at the review and note the amount of backup they have on it. A trusted manufacturer will have no qualms about giving it a substantial warranty offer. However, before you pick a furnace, conduct a background check and confirm if the quality checks are done on each furnace before being supplied in the market.

• Size Of The Induction Furnace

Differently sized furnaces exist in the market allowing small, middle and large scale entrepreneurs to delve in smelting. Before picking a metal melting furnace to invest in, consider the average amount of materials you will be dealing with. A smaller furnace will be insufficient and hence slow you down especially in terms of delivering smelted products. However, a larger one than necessary wastes fuel and increases the production cost.

• Maintenance Of The Induction Furnace

As expected, with technological improvements, advancements in smelting furnaces are being integrated into the machines. Take advantage of this and invest in a furnace that will allow easier operation of gold smelting at home. Factors to focus on should be the kind of maintenance it has especially the frequency. Unlike traditional stove smelting furnaces, you should pick one that has low maintenance and is not labor incentive.

• Induction Furnace Noise Levels

Finally, if you are choosing home smelting equipment, then you want to ensure you can efficiently work on your metals without alerting the whole neighborhood. This means that it should be as quiet as possible. To do this, ensure that the furnace you choose has an insulated blower compartment that minimizes the noise. However, when sound isn’t an issue, then you can eliminate this as a factor of consideration.

Conclusion

Considering your overall needs will be a great help when choosing an induction furnace. Only then will you delve deeper and analyze the number of cycles, run time, number of metals, maximum range and any special requirement of purchasing a silver melting furnace.

LED screens or large screens made of electroluminescent diodes. They display through the combination of red, green and blue lights which merge to create millions of colors. There are a few details you must point out when buying a LED screen. The most significant is the parameter of the screen, for example, the screens pitch or pixel. A right Bibi Led screen has all the parameters that suit your needs. Here are the most important tips while selecting a LED screen.

Notable Tips To Consider When Buying LED Screen

1. Key Parameters

• Resolution

Resolution is the most critical parameter to consider since it determines the clarity of the contents on display. A high screen resolution is necessary to display data, graphics, and numbers which are easy to read and see. High-resolution Bibi LED screens are the ones with LED’s that are incredibly close to each other.

• LED type

There are different types of diodes such as Duel In-Line Package (DIP) LEDs and Surface Mounted Devices (SMD) LEDs. DIP LEDs are used in the outdoor screens while SMD LEDs are used both indoor and outdoor media. The best option is one that suits your purchasing needs.

Note: the brightness of the LED screen depends on whether the screen is placed outdoors or indoors.

• Indoor screens brightness fall between 2500cd/m² and 700cd/m²
• Standard brightness for outdoor screens fall between 7000 and 5000cd/m²
• outdoor screens with high brightness fall between 8000cd/m² and 12000cd/m²

2. Purpose of the screen

LED screens are designed with different parameters to suit different purposes of the screen. The parameters are different as per rental LED screens, LED curtains and LED floor.

• LED floor (Interactive floor)

The most important considerations before selecting LED floor screens include the place where the screen will get positioned, the number of people expected to see the display, the nature of the content to be displayed and lastly the distance of the screen from the viewers.

• Rental LED screens

Portable LED screens are perfect if they will get used in different locations. Rental LED screens are designed with lighter materials. They are fitted with specially designed latches and connectors for easy and rapid assembly and disassembly.

• LED curtains

LED curtains are the perfect option when using an irregular surface. Also, they are the best when making an original and outstanding scene. They can be installed on open spaces, inside buildings or put to hang because of their lightweight. They come in different dimensions and sizes depending on their purpose.

3. Transparent or solid panels

The backing of the LED screen can either be solid or semi-transparent. Semi-transparent panels allow wind to pass through and also reduces the weight of the screen. They are the best for outdoor events. Solid panels are for indoor use because they don’t allow ambient light or distraction bleed through on the contents on display.

Conclusion

LED screens unlike the regular screens can be assembled in different creative ways to suit their use. Their size and orientation are not restricted to a standard size. Make sure the aspect ratio get considered while setting up the LED screen.

ACY is an acronym that stands for Air Covered Yarn; it’s made up of both spandex and DTY. Air covering refers to the combination of more than two yarns to come up with unique yarns that have different characteristics. One of the fabrics that are used is elastic while the other one is non-elastic. The main function of the non-elastic fabric is to improve the durability, evenness, aesthetics, as well as the functional properties of the fabric. ACY can be divided into two:

• Nylon ACY
• Polyester ACY

Companies such as Kabao Industrial Co., LTD specialize in the production of ACY that’s then used to make different types of clothes that are comfortable to wear such as socks, underwear, and swimwear. Air covered yarns have modified elasticity and can be designed for knitted, sewed, and woven fabrics depending on the properties.

The Effects of Air Pressure on ACY

During the production of air covered yarn, an elastic yarn such as lycra and a non-elastic yarn such as polyester are used.  Polyester contains filaments that improve the abrasion resistance and uniformity in length for the ACY.

In the testing of the effects of air pressure on air covered yarn, elastic core spun yarns are used. Lycra is the core material inelastic yarn. The parameters of the air-covering machine are as follows:

• Delivery speed- 110 meters/min
• Air pressure- 4,6,8 kg/cm²
• Elastic draw ratio- 2
• Overfeed to jet %- 5

Here are some of the characteristics that are tested for in the air covered yarn:

• Denier of air covered yarn

The denier of the yard refers to the unit of measurement for the linear mass density of a fiber.

Denier of the filament was calculated after increasing the pressure from 4kg/cm² to 8kg/cm². It was observed that the denier of the yarn increased after increasing the pressure. The increase in denier is as a result of an increase in the bulkiness of the air covered yarn.

• Loop density

The number of loops in the yarn affect its properties and it’s, therefore, very important to measure the number of loops per 1m of yarn when it’s in a relaxed state.

After increasing the pressure, the loop density also increases. This can be attributed to the fact that the height of the loop changes as the air pressure changes; it results in an increase in the number of loops when the length of the yarn remains the same.

• Contents of the components in the yarn

To calculate the amount of lycra and polyester present in 1m of air covered yarn, take the sample and weigh it. After that, separate the lycra from the yarn and weigh the contents separately.

It’s observed that as the pressure increases, the lycra content decreases while the polyester content increases. One can safely conclude that the percentage of the lycra and the polyester varies depending on the pressure variations.

• Stability of the loop

After testing the effects of increasing pressure on the stability of the loops, it’s observed that the instability decreases as the air pressure increases. The decrease in instability caused an increase in loop stability. This is due to the increase in pressure at the binding point in the yarn which causes them to become much stronger hence the increased loop stability.

Conclusion

The process of air covering yarn involves the combination of two or more yarns and results in the formation of yarns with unique characteristics. These characteristics are affected when the air pressure is altered between 4 to 6 and 8 kg/cm².

A change in the pressure has a significant effect on the yarn’s loop density, loop stability, denier of the yarn, as well as the lycra and polyester content. An increase in the pressure results in an increase in the denier of the yarn, polyester content, and loop density. It also results in a decrease in the lycra content and loop instability.
